[Q]: Article: Blind tasting is a very strange activity. Contrary to what many people imagine, it has nothing to do with blindfolds. It involves tasting a wine without seeing the label and it can deliver shocking surprises. I tasted seven champagnes   blind with a group of professionals recently. There was a shock when they discovered the wine most of them preferred carried a label they regarded as their least favorite. That sort of result is especially common with champagne, the most image-driven rather than quality-driven wine of all. But it happens all the time when wine is tasted blind. Because I'm interested in how wines really taste instead of how I think they should, I taste wine blind as often as I can, especially when assessing similar young wines. But blind tasting when you know absolutely nothing about the wine in front of you is something completely different. The most difficult Master of Wine exams include three sessions during which you have a dozen glasses in front of you and nothing more helpful than a printed exam paper asking you to identify each wine as closely as possible, and assess its quality. Now that the MW is behind me, I taste wine completely blind only very rarely, and never in public. So my blind tastings these days are round the dinner table with good friends and once a year when I act as a judge, with Hugh Johnson, in the Oxford vs Cambridge wine-tasting competition. This is the most extraordinary match, always held before the Boat Race but taken just as seriously nowadays. This year's taste-off took place at the end of last month, as usual in the Oxford and Cambridge Club on Pall Mall in London. 
 Answer: Blind tasting is tasting a wine without seeing the label.
[A]: Which of the following is true about Blind tasting?


[Q]: Article: A telescope  , called Gaia, is being designed by astronomers in Europe, and it couldn't be more different from Pan-STARRS, which is another telescope being designed. While Pan-STARRS will be looking for asteroids   and comets headed for Earth, Gaia will be looking at our entire galaxy  . Gaia is designed to draw a map of the Milky Way, our home galaxy. Just as a map of your town gives you a picture of where things are located, Gaia's map of the galaxy will tell astronomers where the stars are. Over five years, Gaia will observe   about a billion stars and other objects in our galaxy. Each object will be observed about 70 times. Gaia will be sent into space connected to a rocket. It contains two telescopes, each focused at a different angle  . These two telescopes act like Gaia's "eyes". The reason why humans can see things in 3D is that we have two eyes focused on the same object, at slightly different angles. By using two telescopes like eyes, Gaia can produce the first 3D map of the positions of the stars it views. Gaia, which is to be sent into space in 2011, will be a powerful telescope. If you were to use it on Earth, for example, you could stand 600 miles away from your best friends and still get a clear picture of their hair. Gaia is one of more than a dozen telescopes being designed by scientists right now. The next generation of telescopes will reveal new parts of our universe that will seem surprising. The universe, with all its planets, stars and other strange objects, is a puzzle with pieces that we can see by using powerful telescopes. 
 Answer: 2 .
[A]: How many different angles can Gaia focus at each time?


[Q]: Article: Biomass energy , often forgotten as promising alternative to oil, received its day in the sun with the gathering of the Bio-Energy World Congress and Exposition in Atlanta, Georgia, late in April, 2007. Nearly 1700 scientists, businessmen and policy-makers, one-quarter from the foreign nations, gathered for a week to discuss various means of squeezing usable energy out of trees, crops, sea plants and urban waste. Biomass energy in the prefix = st1 /United Statescontributes 2.5 percent of the total supply, but this amount can be doubled by 2017 and then doubled again by the year 2027.   Eight percent of Sweden's energy supply, for example, is presently coming from wood and pulp  remaining. Swedenintends to raise this percentage by more intensive harvesting of waste food lying around in forests, and through the planting of so-called energy forests of fast-growing trees such as willow.   Brazilis frequently pointed to as a nation with a major successful investment in energy coming from grains: it presently runs 330,000 automobiles on a water and alcohol mixture, replacing 10 percent of its previous oil supply. Brazilian representatives at the conference said they wish to double this in five years, with a final goal of total replacement. Most of the cars are built at the factory to use the mixture, while older models are changed through low-cost government programs. 
 Answer: Three-quarters of the representatives were from theU.S.
